The Ignite UI for Angular Snack Bar component provides feedback about an operation with a single-line message, which can include a link to an action such as Undo. The Snack Bar message appears above all other screen elements, located at the bottom of a mobile device screen or at the lower left of larger device screens.

Snackbar Demo


To start using Ignite UI for Angular components in your own projects, make sure you have configured all necessary dependencies and have performed the proper setup of your project. You can learn how to do this in the installation topic.


To get started with the Ignite UI for Angular Snack Bar, let's first import the IgxSnackbarModule in our app.module.ts file:

// app.module.ts

import { IgxSnackbarModule } from 'igniteui-angular';

    imports: [..., IgxSnackbarModule],
export class AppModule {}

Show Snackbar

In order to display the snackbar component, use its show() method and call it on a button click. Use the message input to set a text message.


<button igxButton="raised" (click)="">Delete Message</button>
    <igx-snackbar #snackbar message="Message deleted"></igx-snackbar>

If the sample is configured properly, a snackbar appears displaying a text message when the button is clicked.

Hide/Auto Hide

Once opened, the snackbar disappears after a period specified by the displayTime input which is set initially to 4000 milliseconds. This behavior is enabled by default but you can change this by setting autoHide to false. In this way, the snackbar will remain visible. Using the snackbar hide() method, you can close the component in the code.


<button igxButton="raised" (click)="">Send message</button>
  <igx-snackbar #snackbar message="Message sent" [autoHide]="false" actionText="CLOSE" (onAction)="close(snackbar)"></igx-snackbar>
// sample.component.ts

public close(element) {

If the sample is configured properly, a snackbar appears when the button is clicked showing message and action button. The auto hide feature is disabled and the snackbar disappears on 'CLOSE' button click.

Display Time

Use displayTime and set it to an interval in milliseconds to configure how long the snackbar component is visible.


<button igxButton="raised" (click)="">Send message</button>
  <igx-snackbar #snackbar message="Message sent" displayTime="1000"></igx-snackbar>

If the sample is configured properly, the snackbar auto hides faster.

Snackbar in list

Having all main snackbar features covered, we can integrate this component in more interesting scenario. We can use the snackbar to provide a notification and ability to revert actions.

Let’s create a list with contacts that can be deleted. When an item is deleted, a snackbar is displayed containing a message and a button to undo the action.

    <igx-list-item [isHeader]="true">Contacts</igx-list-item>

    <igx-list-item igxRipple="pink" igxRippleTarget=".igx-list__item" *ngFor="let item of navItems">
        <div class="item-container">
            <div class="contact">
                <igx-avatar [src]="item.avatar" roundShape="true"></igx-avatar>
                <div class="contact__info">
                    <span class="name">{{item.text}}</span>
            <span igxButton="icon" igxRipple igxRippleCentered="true" (click)="delete(item)">
                <igx-icon color="#ff5252">delete</igx-icon>


    <igx-snackbar message="Contact deleted" actionText="Undo" (onAction)="restore()"></igx-snackbar>

import { Component, OnInit, ViewChild } from "@angular/core";
import { IgxSnackbarComponent } from 'igniteui-angular';

public snackbar: IgxSnackbarComponent;
public navItems: any[];
public deletedItems = [];

constructor() { }

public ngOnInit() {
    this.navItems = [{
        avatar: "assets/images/avatar/2.jpg",
        text: "Richard Mahoney"
        avatar: "assets/images/avatar/4.jpg",
        text: "Lisa Landers"
        avatar: "assets/images/avatar/14.jpg",
        text: "Marianne Taylor"
        avatar: "assets/images/avatar/17.jpg",
        text: "Ward Riley"

public delete(item) {
    this.deletedItems.push([item, this.navItems.indexOf(item)]);
    this.navItems.splice(this.navItems.indexOf(item), 1);;

public restore() {
    const [item, index] = this.deletedItems.pop();
    this.navItems.splice(index, 0, item);
